Rock Solid

The Adjustable Kettlebell from Rock Solid is ideal for exercises that work major muscles, build power, and burn body fat without needing a whole weight rack to get a great workout. Customization is the name of the game: each piece is actually seven kettlebells in one! You can adjust the weight of the kettlebell at will, to perform high rep or low rep workouts of the same movement by simply adjusting the weighted plates with the slide of the lever.
